Phosphorous acid is used in chemical reactions as a reducing agent that is somewhat less vigorous than the relatedhypophosphorous acid.
Usage:
In industry and agriculture

The most important use of phosphorous acid is the production of phosphonates which are used in water treatment. Phosphorous acid is also used for preparing phosphite salts, such as potassium phosphite. These salts, as well as aqueous solutions of pure phosphorous acid, have shown effectiveness in controlling a variety of microbial plant diseases, in particular, treatment using either trunk injection or foliar containing phosphorous acid salts is indicated in response to infections by phytophthora andpythium-type plant pathogens (both within class oomycetes, known as water molds), such as dieback/root rot and downy mildew.[7]Anti-microbial products containing salts of phosphorous acid are marketed in Australia as 'Yates Anti-Rot'; and in the United States of America, for example, aluminum salts of the monoethyl ester of phosphorous acid (known generically as 'Fosetyl-Al') are sold under the trade name 'Aliette'. Phosphorous acid and its salts, unlike phosphoric acid, are somewhat toxic and should be handled carefully.
Packing : 25kg / 500kg / 1000kg in woven bag lined with double layer polythene bag. The packaging should be marked with "CORROSIVE"sign.
Or using paperboard barred with plastic bag or using plastic weave or Kraft bag with plastic bag inside, net weight 25kgs.
Storage : Dangerous chemical, stored in cool, dry and airiness place, avoid moisture, heat and decay . In transportation, avoid rain and sunlight. Load gently, no breakage. If fire, fight it with water, sand and fire fight machine.

HS CODE: 2811199090

Nature:

Phosphorous acid is a colorless crystal. It can be slowly oxidized to phosphoric acid in the air. When heated to 180 °C, it can be decomposed into phosphoric acid and phosphine (highly toxic). As a dibasic acid, it has slightly ber acidity than phosphoric acid. Phosphorous acid has b reducibility and can easily reduce Ag+ to metal silver. It can also reduce sulfuric acid to sulfur dioxide. It is corrosive and has b hygroscopicity.
Relative Density: 1.651 (21.1 °C)
Melting Point: 73.6 °C
Boiling Point: 200 °C (Decomposes)
Solubility: Easily soluble in water and alcohol.

Soluble ethanol. The air is slowly oxidized phosphate. Heat to 180 ° C is 10% phosphoric acid decomposition and phosphine (toxic). The strong sexual hygroscopicity and deliquescence. A corrosive. By phosphorus trichloride in stirring slowly with water hydrolysis, Phosphite generated by the refining bleaching, cooling system in crystallization. Used in the manufacture of plastic stabilizers, Asian and organic phosphate pesticides.
